    Mysterious Windsor Hum Traced to Zug Island, Michigan. CBC News, May 23, 2014 The source of the mysterious Windsor Hum in the southwestern Ontario city is on Zug Island — in River Rouge, Mich. — according to a federally funded report released today. Essex Conservative MP Jeff Watson released the report's findings at a news conference at the Great Lakes Institute for Environmental Research at the University of Windsor on Friday. Watson said U.S. officials must now determine the precise location of the noise. Copies of the federal report have been given to Michigan Gov.

  • Boats Built at Toledo, Ohio Including Monroe, Michigan
    Boats Built at Toledo, Ohio Including Monroe, Michigan A Comprehensive Listing of the Vessels Built from Schooners to Steamers from 1810 to the Present Written and Compiled by: Matthew J. Weisman and Paula Shorf National Museum of the Great Lakes 1701 Front Street, Toledo, Ohio 43605 Welcome, The Great Lakes are not only the most important natural resource in the world, they represent thousands of years of history. The lakes have dramatically impacted the social, economic and political history of the North American continent. The National Museum of the Great Lakes tells the incredible story of our Great Lakes through over 300 genuine artifacts, a number of powerful audiovisual displays and 40 hands-on interactive exhibits including the Col. James M. Schoonmaker Museum Ship. The tales told here span hundreds of years, from the fur traders in the 1600s to the Underground Railroad operators in the 1800s, the rum runners in the 1900s, to the sailors on the thousand-footers sailing today. The theme of the Great Lakes as a Powerful Force runs through all of these stories and will create a lifelong interest in all who visit from 5 – 95 years old. Toledo and the surrounding area are full of early American History and great places to visit. The Battle of Fallen Timbers, the War of 1812, Fort Meigs and the early shipbuilding cities of Perrysburg and Maumee promise to please those who have an interest in local history. A visit to the world-class Toledo Art Museum, the fine dining along the river, with brew pubs and the world famous Tony Packo’s restaurant, will make for a great visit.

    The Meecheegander Missives: Information on Michigan and Detroit to Prepare Information and Referral Professionals for the 2011 AIRS Conference in the ‘D’ June 5 – 8, 2011 The Meecheegander Missives.doc i The original posts to the AIRS Networker listserve were made daily from April 10, 2011 to June 5, 2011. During June, July, and August, the posts were collected into a single document, corrected when necessary, reformatted, garnished with illustrations pirated from the Internet, and indexed. Final edits were made August 10, 2011. The Meecheegander Missives.doc ii Introduction When it was announced that the 2011 Annual Training and Education Conference of the Alliance of Information and Referral Systems (AIRS) was coming to Michigan, those of us on the board of the local affiliate, MI-AIRS, knew we had our work cut out for us. With the help of Sharon Galler (who has coordinated AIRS Conferences from coast to coast), we divvied up assignments and set to work. I volunteered to write an FAQ for the Conference (a copy of which can be found at the back of this document) to be posted on the MI-AIRS Web site. And I also impetuously volunteered to contribute daily postings promoting the conference to the AIRS Networker , the listserv that’s followed by most people in the profession of community information and referral. It seemed like a good idea at the time. I enjoy writing, and how much work could it take—15 or 20 minutes a day or so? WRONG. It wound up taking a lot more time and effort than I had anticipated.

  • Detroit River International Crossing
    A LOCAL RESPONSE TO THE DETROIT RIVER INTERNATIONAL CROSSING RECOMMENDATIONS TO GUIDE A COMMUNITY BENEFITS AGREEMENT PRODUCED BY THE Urban and Regional Planning Program University of Michigan AT THE REQUEST OF THE Delray Community Council SPRING 2007 The University of Michigan Urban and Regional Planning Program http://www.tcaup.umich.edu/urp/index.html Gary Brieschke Anny Chang Luke Forrest Cassia Heron Kelsey Johnson Rebecca Mark Mariana Orloff Joe Shultz Logan Winston Advisors Eric Dueweke Larissa Larsen EXECUTIVE SUMMARY SUMMARY EXECUTIVE The proposed Detroit River International Crossing (DRIC) has the potential to once again inflict a dispropor- tionate burden on the southwest neighborhood of Delray. Until this point, the Michigan Department of Transportation (MDOT) and its consultant, The Corrodino Group, have maintained a transparent and admi- rable planning process in regards to the proposed crossing. Despite the process, it is our recommendation that the Delray Community Council (DCC) not only partake in the planning process sanctioned by MDOT and the Corrodino Group, but also attempt to create a Community Benefits Agreement (CBA), a signed contract be- tween MDOT and a coalition of neighborhood groups that outlines how Delray and other residents of South- west Detroit can be fairly compensated for the loss of community and quality of life that would invariably oc- cur should the bridge go through Delray. The following report provides the DCC with relevant information pursuant to a CBA. More specifically, the report provides recommendations as to how the DCC should pro- ceed in terms of securing a CBA, and what they should expect to receive from said agreement.

When environmental injustice occurs, there is a question of how to go about solving the issue. Unlike other crimes such as murder, there is no clear offender.
